You're right, there are 4 files produced now, that comment is
incorrect (I just changed it). I left it in broken because I didn't
understand the following:

1) Without the streamer and with the SetEnd/StartPiece, it writes the
5 files (Test.pvti, Test_0.vti, Test_1.vti, Test_2.vti, Test_3.vti)
that I would expect.

2) With the streamer and WITHOUT the SetEnd/StartPiece, it only writes
the 2 files.

3) Setting SetNumberOfStreamDivisions(4) on the streamer or not
calling SetNumberOfStreamDivisions at all did not seem to make a
difference.

Basically the summary of the above is I don't understand
streaming/pieces/etc. Is there a tutorial on this? If not, there
should definitely be at least a few paragraphs we can point to from
examples like this.
